Alpha-ID
Bei der Kodierung per Alpha-ID muss das Element Condition.code mit mindestens einem Coding gefüllt sein, das den Anforderungen der Alpha-ID-Kodierung genügt. Hierzu sollte beim Einbinden des Coding-Profils in das entsprechende Use-Case-Profil ein Binding auf das Alpha-ID ValueSet hinzugefügt werden. Siehe Terminologie - ValueSets.
Die Angabe der Alpha-ID-Version (z.B."2019"), aus der ein Code stammt, ist verpflichtend, da die Alpha-ID nicht versions-stabil ist, d.h. Codes können zwischen den unterschiedlichen Jahrensangaben in der Bedeutung wechseln.

Codes may be defined very casually in enumerations or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information.

Need to be unambiguous about the source of the definition of the symbol.
The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

Hierdurch wird der Tatsache Rechnung getragen, dass jede der jährlich neu erscheinenden Fassung von Alpha-ID ein neues Codesystem darstellt.
Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

| userSelected | Σ | 0..1 | boolean | There are no (further) constraints on this element Element IdShort description If this coding was chosen directly by the user Definition Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).
This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.
Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.
